Chad: Here's a Dayco Poly-Cog PS delete belt # for stock crank pulley: 5060525 (6PK1335). For ASP underdrive crank pulley: Dayco PS delete belt #5060510 (6PK1295). I gained .05 in 1/4 mile by using PS delete belt in my '99 M6 SS car. I gained NOTHING by using PS delete belt in my '02 A4 SS car. That's in 1/4 mile. Tried it many times on the A4 car--no gain. Don't ask me why.... WJ

 

Thanks again WJ

 

I've seen as much a tenth with my car. Albeit, my car is very consistant.

I had to replace my shortbelt recently. I suggest going with at least the 52" belt with an ASP pulley.

 

so you can bypass the ps pump without any problems? i used to do this on my fox mustang with no problem....but then i did it too my 95mustang and it shot ps fluid out of the pump fill. my car is a 99z. looking to do this at the track only. thanks

 

Wow Wil,u get almost a .10....
I gotta try it with my car too.....

Thanx for the info.

 

Same here, I've tried it on at least 4 separate track visits now with the car in various state's of tune and I just don't believe I gained anything. It's a pain in the *** to change back and forth before and after the track, makes that 180 degree turn at the end of the track a bit challenging sometimes and from what I hear can stress a stock steering rack a little bit.
No more short belt for me.

 

ya...typically gives mustangs a tenth...maybe the ls1 unit is more efficient

 

Joel, that was during my SI days.. haven't ran without it since the H/C.
